There’s a few different things going on here. First I’ll go over how basic compilation of multiple files works. If you have multiple files, the important thing is the difference between the declaration and definition of a function. The definition is probably what you are used to when defining functions: You write up the contents … Read more
static, as I think you’re using it, is a means of symbol hiding. Functions declared static are not given global visibility (a Unix-like nm will show these as ‘t’ rather than ‘T’). These functions cannot be called from other translation units. For C++, static in this sense has been replaced, more or less, by the … Read more
Use ldconfig which is the tool that manages link space. The -p flag lets you browse all available linkable libraries.
Mach-O, short for Mach object file format, is a file format for executables, object code, shared libraries, dynamically-loaded code, and core dumps. For unix users this is like a.out but with improvements. This is the format used in Mac OS X and iPhone OS libraries for executable files. As you know iOS devices (iPhone, iPad … Read more
Try the nm utility. GNU nm lists the symbols from object files objfile…. If no object files are listed as arguments, nm assumes the file a.out. [reference]
I’ve managed to solve my problem by using the following: #Dynamic/Shared Libs … #Static start set_target_properties(icarus PROPERTIES LINK_SEARCH_START_STATIC 1) set_target_properties(icarus PROPERTIES LINK_SEARCH_END_STATIC 1) set(CMAKE_FIND_LIBRARY_SUFFIXES “.a”) #Static Libs … #Set Linker flags set(CMAKE_EXE_LINKER_FLAGS “-static-libgcc -static-libstdc++”) This works without passing a -static which creates other big issues, and can essentially mix static and dynamic libraries. As long … Read more
Link 3x faster with gold Since GHC 7.8, you can tell GHC and cabal (at run time without having to recompile GHC) to link with GNU gold. You need in your .cabal file: library: ghc-options: -optl-fuse-ld=gold ld-options: -fuse-ld=gold executable myExecutable ghc-options: -optl-fuse-ld=gold ld-options: -fuse-ld=gold (Note you might want to pass these flags to stack/cabal/Setup.hs on … Read more
This answer assumes that you know basic Linux command. In Linux, there are two types of libraries: static or shared. In order to call functions in a static library you need to statically link the library into your executable, resulting in a static binary. While to call functions in a shared library, you have two … Read more
Object files are source compiled into binary machine language, but they contain unresolved external references (such as printf,for instance). They may need to be linked against other object files, third party libraries and almost always against C/C++ runtime library. In Unix, both object and exe files are the same COFF format. The only difference is … Read more
Check out Building Objective-C static libraries with categories: Objective-C does not define linker symbols for each function (or method, in Objective-C) – instead, linker symbols are only generated for each class. If you extend a pre-existing class with categories, the linker does not know to associate the object code of the core class implementation and … Read more
